Es sind Standleuchten für Wohnräume, Arbeitsräume u. dgl. bekannt, bei denen die Leuchte am Ende eines meist rohrförmigen Auslegers befestigt ist, der sowohl in seiner Längsrichtung als auch in der Höhe verstellbar an einem Ständer mit kreisrundem Querschnitt gehalten, in einzelnen Fällen auch noch um die Ständerachse schwenkbar ist. Zur Befestigung des Auslegers am Ständer dient dabei beispielsweise ein starrer Körper mit zwei sich kreuzenden, aber nicht schneidenden Bohrungen, von denen eine den Ständer, die andere den Ausleger mit geringem Spiel aufnimmt und in denen Ausleger und Ständer durch je eine Klemmschraube festgelegt werden. Bekannt ist ferner eine Standleuchte mit den eingangs genannten Eigenschaften, bei der sich Ständer und Ausleger unter gegenseitiger Berührung kreuzen und durch ein Klemmstück zusammengehalten werden, das in der gemeinsamen Tangentenebene von Ständer und Ausleger unterteilt ist und dessen Hälften je eine gegen die Teilungsebene offene, rinnenartige Ausnehmung mit gerundeten, dem halben Umfang des Ständers einerseits und des Auslegers andererseits angepaßten Böden enthält, und die durch zwei Federn gegeneinander und gegen Ständer und Ausleger gedrückt werden, die sich am Kopf und an der Mutter eines die beiden Klemmstückhälften durchsetzenden Schraubenbolzens abstützen. Der sichere Halt des Auslegers am Ständer ist damit von der Reibung abhängig, die durch die Federn zwischen den Berührungsflächen an den Klemmstückhälften einerseits und an Ständer sowie Ausleger andererseits erzeugt wird.There are standing lights for living rooms, work rooms and the like. Known in which the light is on End of a mostly tubular boom is attached, both in its longitudinal direction and in adjustable in height on a stand with a circular cross-section, in individual cases can also be pivoted about the stand axis. It is used to attach the boom to the stand for example a rigid body with two intersecting, but not intersecting, bores, of which one takes the stand, the other the boom with little play and in which boom and Stand can be fixed by one clamping screw each. Also known is a floor lamp with the Properties mentioned at the beginning, in which the stand and boom come into mutual contact cross and are held together by a clamping piece that is in the common tangent plane is subdivided by the stand and bracket and its halves each one open towards the dividing plane, Channel-like recess with rounded, half the circumference of the stand on the one hand and the boom on the other hand contains adapted floors, and by two springs against each other and against stands and cantilevers are pressed, which are located on the head and on the nut of one of the two clamping piece halves support penetrating screw bolt. The secure hold of the boom on the stand is thus depends on the friction created by the springs between the contact surfaces on the clamping piece halves on the one hand and on the stand and boom on the other hand is generated.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte mit den eingangs genannten Eigenschaften so auszubilden, daß Ausleger und Ständer mit einfachen Mitteln rasch und bequem derart miteinander verbunden und auch wieder voneinander getrennt werden können, daß der Ausleger ohne jede Mühe stufenlos sowohl über nahezu seine volle Länge als auch in der Höhe auf dem Ständer verstellt sowie auch um den Ständer geschwenkt und schließlich auch um seine eigene Achse gedreht werden kann. Dabei sollen Ständer und Ausleger in jeder Stellung fest und sicher miteinander verspannt sein, ohne daß dazu von den üblichen Hilfsmitteln, wie Schrauben oder Federn, Gebrauch gemacht wird. Als Haltekraft soll vielmehr lediglich das Übergewicht des die Leuchte tragenden, nach der einen Seite vom Ständer ausladenden Auslegerteils gegenüber dem anderen Auslegerteil ausgenutzt werden. Dabei soll gleichwohl die Verbindung zwischen Ausleger und Ständer so fest sein, daß die Leuchte sich nicht nur für die StandleuchteThe invention is based on the object of providing a lamp with the properties mentioned at the beginning to train so that boom and stand with simple means quickly and conveniently with each other connected and also separated from each other again that the boom without any effort infinitely adjustable over almost its full length as well as in height on the stand as well can also be pivoted around the stand and finally rotated around its own axis. Stand and boom should be firmly and securely braced together in every position without the usual aids such as screws or springs are used for this purpose. As a holding force Rather, it should only be the preponderance of the one carrying the lamp, on one side of the stand overhanging boom part can be exploited compared to the other boom part. It should nonetheless the connection between the bracket and the stand must be so tight that the lamp is not only suitable for the Floor lamp

Verwendung in Wohnräumen und ruhigen Arbeitsräumen, wie Zeichensälen und Büros, eignet, sondern auch für Werkstätten usw., in denen mit Erschütterungen gerechnet werden muß.It is suitable for use in living rooms and quiet work spaces such as drawing rooms and offices also for workshops etc. where vibrations are to be expected.

Die Erfindung erreicht das bei einer Standleuchte mit einem Standrohr und einem dieses kreuzenden, an einem Ende die Leuchte tragenden Auslegerrohr, die unter gegenseitiger Berührung durch ein auf dem Ständerrohr verschiebbares und um dessen Achse drehbares Klemmstück verbunden sind, in dem das Auslegerrohr längsverschiebbar und um seine Achse drehbar geführt ist, erfindungsgemäß dadurch, daß das Klemmstück aus einem starren Rahmen besteht, an dem das Auslegerrohr in bekannnter Weise unter dem Übergewicht seines die Leuchte tragenden Teils mit zwei in Richtung seiner Achse entfernten und an verschiedenen Seiten dieser Achse liegenden Punkten anliegt, und daß durch die damit auf das Klemmstück ausgeübte Drehkraft das Klemmstück an das Standrohr in zwei in Richtung von dessen Achse entfernten und an verschiedenen Seiten dieser Achse liegenden Punkten angedrückt wird.The invention achieves this in a floor lamp with a stand pipe and a at one end of the lamp-carrying cantilever tube, which under mutual contact by a on the Stator tube movable and rotatable about its axis clamping piece are connected, in which the Cantilever tube is longitudinally displaceable and rotatable about its axis, according to the invention in that the clamping piece consists of a rigid frame on which the boom tube is below in a known manner the preponderance of its part carrying the lamp with two removed in the direction of its axis and points lying on different sides of this axis, and that by the thus on the Clamping torque exerted the clamp on the standpipe in two in the direction of its Axis distant and lying on different sides of this axis points is pressed.

Um bei einer solchen Leuchte Ausleger und Ständer in irgendeiner Richtung gegeneinander zu verstellen, ist nichts anderes erforderlich, als ein leichtes Anheben des schweren Auslegerteils und Verschieben oder Verdrehen des Auslegers gegenüber dem Ständer. Dabei wird zugleich der Reibungsschluß zwischen allen zusammenwirkenden Teilen weitgehend aufgehoben, so daß Oberflächenbeschädigungen an Ständer und Ausleger beim Verstellen so gut wie ausgeschlossen sind.In order to adjust the boom and stand in any direction in relation to one another in such a luminaire, Nothing else is required than a slight lifting of the heavy boom part and moving it or twisting the boom in relation to the stand. At the same time, the frictional connection between all interacting parts largely canceled, so that surface damage to the stand and booms are as good as excluded when adjusting.

Der das Klemmstück bildende Rahmen besteht vorteilhaft aus zwei zueinander parallelen Stäben, deren lichter Abstand größer ist, als der Durchmesser des dickeren der durch den Rahmen verbundenen Rohre und die untereinander durch zwei zueinander parallele, drehfest an ihnen sitzende starre Zugglieder verbunden sind, deren lichter Abstand gleich der Summe der Durchmesser der beiden Rohre ist. Es leuchtet ein, daß der Abstand der durch die Zug-The frame forming the clamping piece advantageously consists of two bars parallel to each other, whose clear spacing is greater than the diameter of the thicker one connected by the frame Pipes and the one below the other by two parallel, non-rotatably seated rigid tension members are connected, the clearance of which is equal to the sum of the diameters of the two tubes. It it is clear that the distance between the

members connected rods determines the angle at which the boom crosses the stand. In order to clearly determine the vertical plane in which the boom and stand touch each other, the tension members can be designed as disks. To increase the friction between the frame parts on the one hand and stand and boom on the other hand, as well as to protect the stand and boom against scratching in the case of careless adjustment, the bars of the clamping piece can with a friction-increasing coating z. B. made of rubber or rubber-elastic plastic and the tension members have such a coating on their opposing surfaces. The well-known clamping effect that arises between two intersecting rods, one of which penetrates the other, if a torque is generated in one of them by a force exerted on it outside the intersection, has already been used in upright lights, but is ao while the position of the intersection point on the part penetrated by the other part is determined invariably on the position of its hole permeating the other part and thus either a change in the jib extension or a height adjustment of the jib is impossible. In addition, the known type of connection prevents either twisting of the boom about its axis or pivoting of the boom about the stator axis. The invention will be explained using the exemplary embodiment shown in the drawing. 1 shows a side view of the lamp, FIG. 2 shows a plan view of the lamp, and FIG. 3 shows a view of the clamping piece with the two tubes in the direction of the bracket round standpipe 1, from which the lamp 3 'supporting - also round - cantilever pipe 3, which crosses the standpipe 1, preferably horizontally at 4, where it touches the stand laterally , which consists of two rods 6 connected to each other with tensile strength at their ends by a disk S. Disks 5 and rods 6 are fastened to one another in such a way that it is impossible to twist the rods 6 in the disks the angle under which the stand and boom tubes cross each other If both tubes have the same diameter and the clear distance between the rods 6 is 1/3 times the tube diameter, then cross them the bars are at right angles. If the distance between the rods is smaller, the bracket part carrying the luminaire is inclined upwards; if the distance between the rods is larger, it is inclined downwards. In addition, the inclination of the boom is naturally influenced by its diameter. That means: with a given distance between the bars of the clamping piece, the bracket tube part carrying the lamp will be more downwardly inclined, the smaller the diameter of the bracket tube is. The distance between the disks running parallel to the lamp stand is equal to the sum of the diameter of the stand and boom tube. The connection of the stand and boom takes place simply in that both parts are pushed through between the rods 6 of the clamping piece K and the boom is left free. Then this exerts due to the excess weight of its part loaded by the lamp on its side downwardly directed torque on the clamping piece, so that the rods 6 press against opposite sides of the stand, and in this way the clamping piece, bracket and stand are clamped together . The disks 5 of the clamping piece determine the lateral alignment of the boom with respect to the stand and also support the clamping effect, because as a result of the arrangement of the boom next to the standpipe in the clamping piece, a tilting moment also occurs transversely to the common tangent plane of the stand and the boom, which also causes the disks be pressed against the pipes. To achieve a particularly secure clamping effect, it may be advisable to cover the rods 6 of the clamping piece, and optionally also the inner surfaces of the tension members 5, with coatings that increase friction, e.g. B. made of rubber, rubber-elastic plastic or the like. To be provided. In addition to easy handling, versatile use and cheap production, a particular advantage of the invention is that the boom can be adjusted in all directions indicated by the arrows in the drawing on the stand, for which only a slight lifting of the loaded cantilever arm and Holding the clamping piece are required. To lock in the selected position, you only need to let go of these two parts. The invention is not limited to the shape of the parts shown. So it is within the scope of the invention if, for. B. instead of a round one, the bars 6 have a polygonal cross-section, which results in surface or edge contact at the clamping points instead of the tangential ones. Furthermore, the standpipe can have a much larger diameter than the boom tube. The tension members 5 of the clamping piece can be elongated, rectangular or polygonal. Stands and brackets can also consist of solid material instead of tubes, although tubes offer the advantage that the cable can be guided through them invisibly and protected. Finally, the stand and bracket can consist of polygonal profiles instead of round ones, although with the same longitudinal and height adjustability of the bracket in the two directions of rotation, only a gradual and more complicated adjustment of these lamp parts to one another is possible. Finally, the stand can accommodate the boom in a longitudinal slot, although pivoting of the boom about the stand axis is excluded. Patent claims:
